UNS S32205 Duplex 2205 Hex Bolts

UNS S32205 Duplex 2205 Hex Bolts are manufactured for applications requiring high strength, excellent corrosion resistance, and dependable performance in demanding environments. Duplex 2205 combines austenitic and ferritic stainless-steel phases. This balanced microstructure provides high mechanical strength and strong resistance to chloride-related corrosion.

Aanuraj Fasteners manufactures these Duplex 2205 Hex Bolts by hot forging. Solution annealing and rapid cooling are used to achieve the required material properties. Metric and inch sizes are available with coarse, fine, UNC, and UNF threads. Bolts can also be supplied with inspection documentation and material traceability as required.

Key Features

• High Strength: Duplex 2205 provides higher tensile and yield strength than many conventional austenitic stainless steels.

• Excellent Corrosion Resistance: Strong resistance to general corrosion, pitting, and crevice corrosion is provided.

• Chloride Resistance: The alloy performs reliably in chloride-containing and marine environments.

• Stress Corrosion Cracking Resistance: Excellent resistance to chloride stress corrosion cracking is offered by the duplex structure.

• Hot Forged: Hex bolts are manufactured using controlled hot-forging processes.

• Solution Annealed: The material is solution annealed and rapidly cooled to maintain the required duplex microstructure.

• Metric & Inch Sizes: Available in M12–M24 and 1/2″–1″, with other sizes available on request.

• Multiple Thread Options: Metric coarse/fine and Inch UNC/UNF threads can be supplied.

• Material Traceability: MTC and inspection documentation can be provided as specified.
